It appears that two perfectly identical radar guns can resolve a lot of science arguments. One of the most absurd arguments made by Quantum Mechanics mathematicians is that motion can only be measured relative to some object.
That means that if you have two people inside the trailer of a truck traveling at 50 mph, the two people are stationary because there is no object inside the trailer moving relative to them. It doesn't make any difference if they have a cell phone and talk with the driver who tells them what speed the truck is traveling, according to mathematicians they are stationary. Why? Because mathematically, the inside of the truck is a "reference frame" where nothing from the outside can intrude.
Einstein saw that that was just plain STUPID. And he realized that motion can be measured relative to the speed of light. Light is always emitted at c, and light always travels at c, which is 670,616,629 miles per hour. That is the fastest that anything can travel, so all other speeds can be measured relative to that speed.
Radar guns measure the speeds of moving objects relative to the speed of light. In the illustration above, two men with radar guns are pointing their radar guns at each other while the truck moves at 50 mph.
Einstein's second postulate says that light is always emitted at c, regardless of the speed of the emitter. So, both radar guns in the illustration emit photons at c. Radar GUN-A receives photons from GUN-B at c+v because Gun-A is moving toward those oncoming photons at velocity v. Radar GUN-B receives photons from GUN-A at c-v because GUN-B is moving away from the oncoming photons.
According to mathematicians, this is impossible. They claim both radar guns will measure and display a speed of zero, because they believe that radar guns measure the speed of a target relative to the gun, not relative to the speed of light. And in the experiment, the guns are stationary relative to each other. But how do the guns know that? Mathematicians don't seem to be able to answer that question.
